Thanks to BlueDog, Riley and I completed a complete loop around the complex with her at my heels with a loose leash and no physical corrections! She braved the wind and stayed focused on me even with the garbage cans flying around us. We passed 5 dogs all of whom barked/lunged at her. One of the dogs was less than 10 feet away when we passed.
Riley remained by my side, loose-leashed, focused, (though clearly aware of the other dogs) with no aggressive reaction! I noticed a significant difference in her on leash behavior after Eric walked her last week.
I have no question in my mind that it is because of working with you and your team that Riley is as well behaved as she is. Thank you for all your help!
